たくさんの観測が集まった。日本からはツィレッヘナム（Mare
Tyrrhenum;245W,-25)付近の観測となった。ヘスペリア(Hesperia;240W,-20)の
北半分が明るくなった。エリシウム(Elysium;215W,+25)付近は午後になっても
まだ雲は出ていない。D.C.Parkerの画像ではソリス（Solis lacus;90W,-25)の
南側に接続するように明るい点が写っている。　(reported by 15 observers)

July 19th, 2003
A lot of observation centered. It became observation near Mare
Tyrrhenum (245W,-25) from Japan. The northern half of Hesperia (240W,
-20) became bright. Even if it becomes in the afternoon near Elysium
(215W,+25), cloud can not be seen. Bright spot seems to touch the
southern side of Solis Lacus (90W,-25) in the image of D.C.Parker.

３時頃までは雲や薄雲があり透明度も悪かったが、その後薄雲も去った。しかし、シーイングは良くない。

残りの画像を処理したが、薄雲を通して撮像したものもあるため色合わせが難しい。

とにかく厚い雲が一瞬わずかに薄くなるのを待って撮影。ピントも？
Fを小さくして露出も切り詰めた。シンチレーションを乱す雲だったので。
320X240で撮影した。色々な設定に苦労した。雲のせいで。
小さい火星ですみません。
撮影開始からは完全な曇り状態だった。とにかくいい条件で撮影したい。

早朝の火星観測は諦めて、夜半過ぎに見えるようになったため、やっと観測です。
早く好条件の大きな大シルチスを見たいものです。

Dear all
Here my latest Mars image under fair/good seeing and poor transparency.
Strong irregularity on the SPC: a dark rift on the left and a very bright remark close to the central meridian!
Does someone know what they correspond to?

Accettabili condizioni atmosferiche mi hanno permesso di ottenere questa discreta immagine
calda calda di 8 ore fa!
Saluti!

Un'altra ripresa di questa notte, leggermente migliore. Ho inserito tutti i canali, certo che quello IR/R e un mondo a parte!

Gia dal titolo potete intuire come e stato acquisito il filmato che ha originato questa immagine.
Ho ripreso Marte con la Vesta tramite il software K3CCD, che consente anche di acquisire in modalita compressa DivX.
Il film e durato ben 150", a 15 fps, per un totale di 2250 frames.
Con Iris ho mediato i migliori 1300, e fatto una normale tricromia. Con Photoshop ho poi ribilanciato i colori e contrastato ulteriormente l'immagine.
Il risultato mi sembra molto promettente, l'acquisizione con compressione DivX con "bitrate" a 10.000 (la meno spinta) ha permesso di ridurre lo spazio occupato sull'HD dai circa 1000 Mega che sarebbe dovuto essere a soli 21 Mega!!!!! Avrei potuto registrare 50 film al posto di uno!!!!!!
Questo sistema credo possa essere utile a chi ha computer portatili con HD limitato o comunque quasi pieno......
Il problema dopo e solo trovare il tempo di elaborare, magari su un PC senza problemi di memoria....(iris esplode 2250 frames in almeno 7 Giga!!!) utile in tal senso la funzione di ritaglio dei frames, "window2 in out x1 y1 x2 y2 num.frames")
I dati dell'immagine sono tutti indicati, newton da 25 Giacometti con secondario in Astrositall Marcon.

Hi all
Here are my first Mars images since February. The altitude is low (25 degs) and
conditions are very difficult, but the resulting images do reveal the albedo markings
clearly. Sinus Meridiani is prominent, as is the pointed Oxia Palus.
Maybe better when the weather improves...
Best Wishes

Total Exposure times: 260 x 0.04 secs.
Seeing variable/poor (Pickering 0-5.) at 25 degrees.
Seeing good (Pickering 6-8) at 60 degrees.
Transparency variable with frequent & increasing low clouds.
Wind SW (0-5mph.) Light dew.

Hi all : the conditions were again good to very good on the morning of july
19. Here are the images. The darkened Mare Serpentis looks impressive !
I'm currently observing - images will follow, much later. It tooks much time
to process all the movies...

Dear friends
I got very nice steady seeing this morning (at 360x !), AVI files
not yet processed. Starting from Saturday morning (July 19), there was a
strong evidence of Argentus Mons and Novissima Thyle with my "little" 4"
refractor (Perl-Vixen fluorite 102mm F/D=8,8 with tele-extender, barlow
2x and VestaPro webcam on Super-Polaris mount). Remember that Airy disk
diameter is 2,8" ! A small topographic white patch is obvious between
Meridiani S. and Margaritifer S. on July 19 image (blue and composite).
However, processing rules are not well defined and there are some
problems with RGB channels calibration. Waiting for IR-cut filter.
Best regards
